  • Network protocol series — TCP, UDP, socket and reference model


    preface To tell you the truth, this article is a bit empty, because I don’t usually study this area, and then it involves too many knowledge points. I can only look around and summarize the relevant information, so I just want to say:The content of this article only represents personal position, and mistakes must be […]

  • Computer network — basic knowledge (1)


    1. Why does socket provide an interface between the application layer and the transport layer and not between other layers? From the analogy operating system and the details of their respective concerns 2. TCP handshake and wave and data transmission process? 3. Why does the active shutdown party stay in time when TCP waves its […]

  • Implementation of high concurrency server with PHP


    When it comes to high concurrency, there is no way to bypass the I / O reuse, and then to the specific platform Linux, there is no way to bypass epoll. Why epoll is efficient is not discussed. Interested students can search for it by themselves, or use the ready-made swote directly. The principle is […]

This kind of conflict is universal, but this paper only analyzes the nature of the problem, not the higher level of abstraction. I am writing a resource protocol similar to HTTP, called RP, resource […]

  • Understanding of the five layer model as a whole


    After the birth of the computer, the powerful computing function makes people think about whether the computer can communicate with each other. However, people have found that the communication process is very complex and requires a variety of protocols to maintain the stability of the communication process. Therefore, the OSI seven layer model was born, […]

  • About UDP protocol


    Recently, when reviewing the knowledge of computer network, I didn’t study it carefully in class before. I only remember a few high-level terms. So take advantage of this review and record the learned knowledge in the form of a blog, so as to deepen my impression. Secondly, I hope you can have a deeper understanding […]
